JoHN n. MARSDEN, or PHILADELPHIA, PENNSYLVANIA CUSHIONED GLASSRECEPTACLE.

y Application led April 7,`

of glass together with casing and cushion` means for enclosing andsupporting the glass battery jar. Among the objects of the invention isto provide ay storage battery or its equivalent having an acid proofcell structure, a strong casing of insulating material, and a cushion ofpacking material of a strong and durable nature interposed between thecell structure and the casing. n o

Another object ofthe inventionis to provide a storage battery having aglass cell structure with partitions therein for individualy groups ofelectrode plates and a cushio-ning casing enclosure for the cellstructure and having arranged suitable windows for the observation ofthe condition of the electrolite in the several cells. j A still furtherobject of thefinvention is to provide an acid proof structure, aninsulating supporting casing, and a cushion ofL non-hardening leak proofcompositionbetween the cell structure and the casing.

With the foregoing and other objects in view the invention consists inthe arrangement and combination of parts hereinafter described andclaimed, and while the invention is not restricted to the exact detailsof construction disclosed4 or suggested herein, still for the purpose ofillustrating a practical embodiment thereof reference is had to ytheaccompanying drawings in which like reference characters designate theysame parts in the several views, and in which- Figure 1 is a verticallongitudinal section of a preferred embodiment of the invention on theline 1-1 of Fig. 2.

Y Fig. 2 is a plan view of the same, parts being broken away. Fig. 3 isa vertical transverse section on the line 3-3 of Fig. 1.

Fig. 4 is a side elevat-ion. Referring now more specifically to thedrawings I show a storage battery or its equivalent comprising threeprincipal parts. A cell structure 10 made preferably Vof glass andhaving some of the characteristics of the cell structure illustrated anddescribed' in my co-pending companion application, filed of even dateherewith, Serial No. 181,- 642, the same having a plurality of verticalpartitions l1 integral with the bottom 12 1927. serial Np. 181,643.Y

and extending upward therefrom to the.v top of the receptacle and havingalso longitudi nally arranged projections or plate rests 13 integralwith thebottom and lower portions thereceptacle or cell structure 10 maybe variously designed according to the'shapey of the partitions andextending upward from the bottom. The bottom surface ofcellulose,parlin, or the like. This casing is substantially parallel to the outersurface of the receptacle 10 and extends upward slightly above it at 14ato provide for a lid or cover, not shown, the cover to come within thetop portion of the casing. Either or both sides of the Vcasing areprovided with a series of windows or sight openings 15 corresponding toand registering with the majority of the cells formed in the receptacle10 between the partitions 11. These windows extend upward to asubstantial distance so asto enable the observer to notice the height ofthe electrolitein the cells and into which the plates, not shown, areplunged.

`The construction of the cell fillers, not be-k ing a part of my presentinvention, is not elaborated uponin this specification.V

At either side wall of the casing, preferably at the ends thereof andopposite-each other, are a pair of handles 16, each made of sheet metaland mainly flat throughout,

and from the body of whichv are `struck 'a plurality of prongs 17adapted to be driven Filling the space between the receptacle 10V andythe casing 14, said space being of unit form lcross section except wherethe handlesV are interposed, is introduced a mass of plas- .ticmaterial/19 of a non-hardening composiktion such as asphalt tar or thelike, the same filling the entire space up to the upper edge of thereceptacle 10, making a complete cover for the bottom and sides of thereceptacle and being furthermore of such a composition as to constitutea cushion, preventing break# ilo age or damage to the receptacle Whenthe construction is subjected to rough usage, and serving, furthermore,as a self sealing means for the receptacle Wallsy should perchance acrack or flaw develop therein. rlhereby the electrolite or acidcomposition carried by the receptacle will be prevented from dripping orspilling and the danger of short circuits will be practicallyeliminated.

I claim:

l. In a battery container, an inner receptacle of transparent materialhaving a bottoin and side Walls, a casing surrounding and spaced fromthe receptacle, and a cushion filling the space between the receptacleand the casing and guarding the receptacle from damage, the casing andcushion being provided With registering' sight openings in the sidethrough which the receptacle and the interior conditions of thereceptacle may be observed.

2. A battery container as set forth in claiin l in which the receptacleis of vitreous material and the cushion consists of a viscous,non-hardening composition adapted to seal automatically any flaws or thelike that may develop in the receptacle.

3. A battery container as set forth in claiin l in Which the receptacleis of molded glass and includes upright partitions integral With thebottoni and side Walls, forming independent cells, and the registeringsight openings pertain to a plurality of cells respectively.

In testimony whereof I affix my signature.
